If she plans to abolish the holiday entirely and make Election Day a federal holiday/day off work or school.
I support this whole-heartedly. In Puerto Rico, Election Day is a holiday.
It'd give the American people a day off in the lead up to Thanksgiving (which also makes an extra opportunity for Thanksgiving preparation/Christmas shopping), increases turnout and the ability of the candidates to reach more people in last minute advertising/appearances. It's accomplish more than "Native American Day."
